2022 ICD-10-CM Code H10.9
Unspecified conjunctivitis
Valid for Submission
| ICD-10: | H10.9 |
| Short Description: | Unspecified conjunctivitis |
| Long Description: | Unspecified conjunctivitis |
Code Classification
H10.9 is a billable diagnosis code used to specify a medical diagnosis of unspecified conjunctivitis. The code H10.9 is valid during the fiscal year 2022 from October 01, 2021 through September 30, 2022 for the submission of HIPAA-covered transactions.
The ICD-10-CM code H10.9 might also be used to specify conditions or terms like bacterial conjunctivitis, bilateral conjunctivitis, conjunctivitis, conjunctivitis associated with autoimmune skin disorder, conjunctivitis associated with autoimmune skin disorder , conjunctivitis associated with epidermolysis bullosa, etc.
Unspecified diagnosis codes like H10.9 are acceptable when clinical information is unknown or not available about a particular condition. Although a more specific code is preferable, unspecified codes should be used when such codes most accurately reflect what is known about a patient's condition. Specific diagnosis codes should not be used if not supported by the patient's medical record.

Clinical Information
- CONJUNCTIVITIS-. inflammation of the conjunctiva.
- CONJUNCTIVITIS ACUTE HEMORRHAGIC-. a highly contagious disease characterized by subconjunctival hemorrhage sudden swelling of the eyelids and congestion redness and pain in the eye. epidemic conjunctivitis caused by enterovirus 70 ev 70 was first described in africa in 1969. it is caused also by coxsackievirus a24 variant ca24v. epidemics by this organism have appeared most frequently in asia.
- CONJUNCTIVITIS ALLERGIC-. conjunctivitis due to hypersensitivity to various allergens.
- CONJUNCTIVITIS BACTERIAL-. purulent infections of the conjunctiva by several species of gram negative gram positive or acid fast organisms. some of the more commonly found genera causing conjunctival infections are haemophilus streptococcus neisseria and chlamydia.
- CONJUNCTIVITIS INCLUSION-. an infection of the eyes characterized by the presence in conjunctival epithelial cells of inclusion bodies indistinguishable from those of trachoma. it is acquired by infants during birth and by adults from swimming pools. the etiological agent is chlamydia trachomatis whose natural habitat appears to be the genito urinary tract. inclusion conjunctivitis is a less severe disease than trachoma and usually clears up spontaneously.
- CONJUNCTIVITIS VIRAL-. inflammation often mild of the conjunctiva caused by a variety of viral agents. conjunctival involvement may be part of a systemic infection.
Diagnostic Related Groups - MS-DRG Mapping
The ICD-10 code H10.9 is grouped in the following groups for version MS-DRG V39.0 What are Diagnostic Related Groups?
The Diagnostic Related Groups (DRGs) are a patient classification scheme which provides a means of relating the type of patients a hospital treats. The DRGs divides all possible principal diagnoses into mutually exclusive principal diagnosis areas referred to as Major Diagnostic Categories (MDC). applicable from 10/01/2021 through 09/30/2022.
| MS-DRG | MS-DRG Title | MCD | Relative Weight |
|---|---|---|---|
| 124 | OTHER DISORDERS OF THE EYE WITH MCC | 02 | 1.3988 |
| 125 | OTHER DISORDERS OF THE EYE WITHOUT MCC | 02 | 0.8354 |
The relative weight of a diagnostic related group determines the reimbursement rate based on the severity of a patient's illness and the associated cost of care during hospitalization.

Information for Patients
Pink Eye
Conjunctivitis is the medical name for pink eye. It involves inflammation of the outer layer of the eye and inside of the eyelid. It can cause swelling, itching, burning, discharge, and redness. Causes include
- Bacterial or viral infection
- Allergies
- Substances that cause irritation
- Contact lens products, eye drops, or eye ointments
Pink eye usually does not affect vision. Infectious pink eye can easily spread from one person to another. The infection will clear in most cases without medical care, but bacterial pink eye needs treatment with antibiotic eye drops or ointment.
